While recording the video, camera keeps moving

[Dhara02]

Dear members, as I record my teaching lectures with help of samsung galaxy note 10, lens of its keep on moving and it goes out of my white board. How can we fix camera on that white board only. I think its motion sensitive so when I goes to left it goes more to left and gets out of white board and in similar way for right side. 

It should record the same area which we have fixed in while starting the recording.

Try to select Auto tracking option from camera settings...it will help in selecting focus...
